NFS traditionally doesn't use any encryption, so anyone on the network can
eavesdrop. It's actually even worse than that because there's no
real authentication either, so they can easily access the files.
All in all it's pretty bad.

WEP only protects in the sense that it tries to control access to your
network, but the problem is what happens to people who do have access to
your network (or who break WEP).

Then use NFS over TCP, that's been available for a while now.
